Gas pipeline monitoring in Europe by satellite SAR [PDF]

open access: yesSPIE Proceedings, 2003
At present, gas pipeline networks in Europe are routinely monitored by vehicle and air patrols to protect them against damage by soil movement and third part interference. Because of the expenses, pipeline operators are investigating the possibilities to replace these traditional monitoring methods by remote sensing from space.
